I recently purchased a 1988 Nissan Pathfinder with a blown head gasket. The previous owner said that the original 3.0L engine had been replaced with a 3.3L engine. He didn't know what the 3.3L came out of. I have noticed in all of the videos I have watched that the oil filter on the 3.3L engine is in the front of the engine on the drivers side. On my engine, the oil filter is on the passengers side. If you take off the passenger side front tire, it's right there. Of course before I order everything I need for the head gasket replacement, I need to know what I'm ordering. I was wondering if anyone knew what year 3.3 had the oil filter over to the passenger side? Any help would be appreciated.
